The above polymer rates are indicative and vary from time to time. Rates of Indian plastic resin manufactures are ex-works in Indian rupees per metric ton exclusive of taxes Freight/Transport, excise, sales tax and other levies onmaterial if any will be payable extra as applicable.
Mechanical Properties of Real Polymers We've been talking abstractly for a long time, now, so it would probably be a good idea to talk about which polymers show which kinds of mechanical behavior, that is, which polymers are strong, which are tough, and so forth.
Materials as a field is most commonly represented by ceramics, metals, and polymers. While noted improvements have taken place in the area of ceramics and metals, it is the field of polymers that has experienced an explosion in progress.
Heat exchangers constructed of polymer-based materials could offer an alternative . to metallic heat exchangers. The use of high thermal conductivity polymer com-posites in place of copper and aluminum could reduce materials costs and overall manufacturing costs, and provide energy savings during manufacturing and end use.
In other words, it costs nearly $6000 to achieve a relatively rudimentary database for one grade of one polymer. When you consider that there are perhaps 20,000 grades of polymers in use worldwide, you can clearly see the prohibitive cost involved.
(Flexible Packaging Materials) Properties. ... LLDPE offers a better balance of stiffness and toughness and allows for thinner films, and thus, reduces material cost. Polymer Properties Database Free Polymer Information Source. A-Z Polymer Data. Theromophysical key data on over
Against steel which has density of 7850 kg per cubic metre. MECHANICAL BEHAVIOUR OF POLYMERS. Polymer materials show a great range of mechanical properties and in a single material the mechanical response may change appreciably over quite a small temperature range.
PEEK is a high temperature, high cost , semi-crystalline material with excellent mechanical properties and chemical resistance. Tensile Strength 14,000-41,000 psi with carbon fiber
Polymers are materials with a seemingly limitless range of characteristics and colors. Polymers have many inherent properties that can be further enhanced by a wide range of additives to broaden their uses and applications.
With increased attention to product safety, the use of fl ame-resistant polymers for molded electrical enclosures is growing. Some polymers like vinyl are inherently fl ame-resistant, while other polymers require additives to make them more fl ame-resistant. These additives can signifi cantly alter the properties and performance of the base polymer.
1 Tie layers are functional polymers coextruded between two chemically different polymers to improve the adhesive strength and to prevent delamination. 2 The combination of HDPE with (butene or octene) LLDPE offers a better balance of stiffness and toughness and allows for thinner films, and thus, reduces material cost.
